A reliable analysis first separates the literal model and figurative target, then tests whether they can coexist. In aḥyaynāhu, the steps are:
1. Source: giving life in its familiar sense.
2. Target: the vitality of guidance.
3. Common feature: the emergence of benefit and effective activity; the context identifies guidance.
4. Classification: someone physically alive can also be guided, so the metaphor is concordant.
The common feature explains the transfer. Coexistence determines this particular classification. Combining those two tests produces mistaken labels.
